On 8/17/09 on a flight from DFW to LGA, shortly after take, the announcement re items for purchase in Y, was "...there may be limited
quality for items to be purchased", she immediately corrected herself quantity instead of quality.
Years back when airlines began to cut (free) meals on domestic flights on a UA JFK/MIA flight (when UA had a much bigger presence at JFK) the FA began to tell Y paxs about the lovely dinner service when she was interrupted by another FA. She then had to get back on the PA and tell the paxs that dinner was no longer being served (prior to BOB).
